将[]放在列名称周围。例如：物品ID = [物料ID] 对所有列名称执行此操作

SELECT Item ID as [Item ID], " & _
                                     "Item Name as [Item Name], " & _
                                     "Item Type as [Item Type], " & _
                                     "Quantity as [Quantity], " & _
                                     "Min Shelf Stock as [Min Shelf Stock], " & _
                                     "Purchase Price as [Purchase Price], Note " & _
                                     " From Product ORDER BY Item ID",

更改为：

SELECT [Item ID], " & _
                                     "[Item Name], " & _
                                     "[Item Type], " & _
                                     "[Quantity], " & _
                                     "[Min Shelf Stock], " & _
                                     "[Purchase Price], Note " & _
                                     " From Product ORDER BY Item ID",
